Yea Paul it was on roo we didnt chase the tune at all. put some timing and boost into it and that was it.

wont be long till we race it i still have to put the auto in it and gas it{ i know gas is for fags IM GAY}

Paul what sort of power did your car make on a race tune? just curious not taking the piss at all :P

less power than you... :P ...with slightly less boost. Very safe tune though.

We thought it best to get the car set-up and running good consistant times with a sensible tune and reasonable boost levels. Ringing the engines neck while trying to get the set-up right is a bit silly as these engines have a short life at 1000hp+. Its now set-up right and quite consistant as the last 6 or 7 passes have been 9.7's or better with all the 60' times being in the high to mid 1.3's. Mark says there is lots left in it (about another 120hp at the treads with further boost and tuning) so ill be flying back up in a few weeks to run it again with a bit more power and set-up in the car. Small steps are the order of the day...trying big jumps can leave you frustrated and or a big expensive mess to fix.

any idea of how long till you take it out? remember the suspension guide i gave you...its a good starting platform and easier to fine tune from there.

good luck

Thanx mate. it wont be for about a month or two ive got other things going on{work shit}

so i still have to bolt the auto in and get shafts made but i will let you know

i know its easy enough to make the power we just have to get it down the track

Ok dyno dynamics could read high but knock 200kw off the figure and im still making 300kw more than most :P

i lol'd.....to save an arguement...get Vic to do it in 'Shootout' mode...its the industry standard and cross-references directly to Mainline figures.

dyno's are for tuning anyway...racing is the true measure of performance.

id like to see it run so stay in touch before you take it out.

Haha its been a while since the last "flame someones dyno figures" session on here.

Nice work Superjet, sounds like a very impressive setup - be good to hear how it goes on the strip. I know RIPS has run around 150mph in a full weight R34 GTR without NOS and slightly less boost on an RB26/30 with the same or less amount of "turbo" so while I can't make heads nor tails of how different Oz dynos read, I know that if your head is good and the tune is nice - a 26/30 with a bunch of turbo, good fuel and 30psi can make for a very hearty amount of power.

Well done mate, glad it worked out well for ya.

Was good talking to Con last week, we discussed a few things and I told him to go for it as we'd been alot further than you wanted to go with the same bottom end setup.

Best of luck mate, get the gas on there and let me know how me old auto goes too :D

Rob is this the Turbo400 4WD you been working on?

Nah, this is a different set up alltogether.

The TH400 is all but done, I'm just waiting for the car to get here from overseas thats going to be our test mule.

    • As I've said elsewhere, I am using the stock intercooler piping path in the engine bay, and a return flow cooler, and making ~250 rwkW (without any effort put into trying to turn it up past there just yet) and expect to be able to make some more, and frankly, I would be perfectly happy with 260-270rwKW. This is peak road Skyline usability territory. You go past there and, sure, the car will snap necks more when it's on boost, but it will also break shit all the time, cost a (even larger) fortune in tyres, etc etc. Anyway, I also do not like the over-the-fan pipe path, and you don't have to do it.
    • I see, honestly I’m not too fussed about the looks. The only reason to go plenum is to make the piping easier instead of the classic over the rad etc. 
    • Not easy to quantify wrt something like how many fractions of a second slower it would be over 0-100. But given that a 250-300rwkW car is able to do that launch sprint in 5-6 sec (and faster with appropriate tyres, and surface)..... giving up as much as a second would feel like torture. A ~450HP capable turbo is not going to make lots of boost in the 2000-3000 rpm range. So, whilst with some boost on hand it will be faster accelerating in that rev range than your engine currently is NA, it will not feel like a fast car until the boost is solidly in. You know what your car feels like right now when you open it up at 2000rpm. if you've ever been in an actual fast car, you will appreciate that the NARB25 is.... not exciting. Well, add some boost and it will be better. But shorten the intake runners and it might not be better at all. It might come out better, but it could end up feeling the same. For me, it's not the 0-X km/h sprints that matter. It is easy to fry the tyres with anything over 200 rwkW. You can't use all the power available in 1st and 2nd anyway, you have to modulate the throttle. What matters is how the car reacts when you're driving in traffic in 4th or 5th and have maybe 2000 rpm on board, and you want/need to add some speed quickly, and don't have time for the downshift. It won't make boost, it will be all NA (at the speeds we're talking about - remember how fast you're going at 2000 in 4th! and don't plan on breaking the limit by too much.) So giving away NA torque is not what I would consider practical for a street car. And retaining that NA torque builds boost faster which makes the car faster. The flashy plenum is not actually better, unless you're looking at a track car where you can keep it on the boil all the time.  
    • So how much difference does it make you think? Like 1 second in the 0-100?  I was have smaller turbo so hopefully that spools quick GTX2871.  currently it’s NA so you can imagine pretty slow, but I do want fast accusation a little as there’s not many places I’ll be driving where I go over 80 even near me. So 0-60 and 0-80 targets
